Celestia noticed Luna doesn't get out much, so she decided a fun summer trip to the water park was a good idea, though Luna waited until it was too late to reveal to her sister she cannot, in fact, swim x'D.
I wanted to draw something with a lot of water, because it's super hot this summer, and I wish so badly I could chill at a water park. I'm melting! There hasn't been hardly anything I can suffer in this heat to do other than draw and read.
Luna/Celestia belong to Hasbro, art belongs to me.
